This is a new JPI harness/adapter for connections to one of their primary engine monitors, and perhaps the older non-primary units. Spruce has it here:
https://www.aircraftspruce.com/catalog/ ... -06623.phpI bought this as it was needed for my Electroair installation, and I put it in a safe place before I got to the installation last year. After turning the hangar inside-out, I ordered another one to proceed with the installation. I have an EDM-900 and used a Bendix adapter originally to sense RPM, but with the EA system I needed this unit to take the electrical signal and feed the EDM. Turns out it was in my home office and not the hangar!
Package was opened to look at the schematic, but otherwise un-touched. $150 shipped to you.
